The system includes interconnected waste water pipes containing two separate passageways, one for reusable grey water and the other for sewer water, and three different types of T-fittings used with the two passageway waste water pipes, each T-fitting designed to interconnect two axially aligned waste water pipes and having an offset opening to one of the waste water passageways in the fitting, one type of T-fitting designed to discharge sewer water into the sewer water passageway in the fitting, the second type designed to discharge grey water into the grey water passageway of the fitting, and the third type designed to vent to the atmosphere both passageways in the fitting. The system also includes a fourth T-fitting designed to divert the reusable grey water flowing in one of the aforesaid two passageway pipes into a storage tank and also to channel the sewer water flowing in the other passageway of the pipe into a public sewer line or septic system.
